UNITED STATES PATENT OFFICE.

MICHAEL SIMON, OF MILLERSBURG, OHIO.

DOOR-SECURER.

SPECIPICATIOTV forming part of Letters Patent No. 343,401, dated June 8,1886.

Application filed April 6, 1886. Serial No. 197,953. (No model.)

To an whom it may concern:

Be it known that I, MICHAEL SIMON, of Millersburg, in the county ofHolmes and State of Ohio, have invented a new and Improved Attachmentfor Locks, of which the following is a full, clear, and exactdescription.

My invention relates to the combination a portable attachment designedmore especially for travelers, the device being so arranged that it maybe quickly and easily secured to the keeper of an ordinary lock, andbeing so secured will effectually prevent the opening of the door fromthe outside.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a view of the inner face of a portion of a door and itscasing, representing my improved attachi'ient as in position upon thekeeper, a portion of the attachment and the keeper being broken away todisclose the location of the upper clamping-screw. Fig. 2 is a side viewof the keeper and attachment, the buffer of the rear screw being shownin section to disclose its construction; and Fig. 3 is a plan view ofthe lock, the attachment being shown in central section, taken on line00 a: of Fig. 1.

The attachment constituting the subject matter of this applicationconsists, essentially, of a malleableiron plate, A, formed with cor nerpieces a a and central flange, b, a horizontal ridge, 0, and bosses d d.Each of the bosses d is centrally apertured, and the aperture so formedis threaded, in order that it may be engaged by clamping-screws B B. Theridge 0 projects beyond the rear of the plate A, and in this projectionthere is a threaded socket, in which there is mounted a screw, 0, uponthe lower end of which there is arranged an iron or rubber buffer, D,that is secured to the screw by means of a swivel-joint, 6. At theforward end of the ridge 0 there is a fourth aperture, in which a fourthscrew, E, is mounted, the plate being curved outward from each endtoward the forward end of the ridge 0, as clearly indicated in Fig. 1.

The attachmentv described is secured to the keeper F of the ordinaryform of rim-lock G, the attachment being held in place by means of theclampingscrews B B, one of which is forced against the under side of thekeeper, while the other is forced against the upper side of such keeper.The screw 0 is then turned so that its buffer will be brought to bearagainst the casing of the door at a point just beyond the keeper, andthe screw E is advanced until its blunt point strikes against the faceof the lock, so that there will be no possible play between theattachment and the door, and the attachment being placed in position itwill be impossible to open the door from the outside of the apartment.

Such a device as I have described constitutes a cheap,efficient,anddurable attachment applicable to the ordinary form of rim-lock, and willbe found to bea most useful addition to the travelers outfit, as well asan exceedingly useful article for general use in private houses.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. As a new article of manufacture, an attachment for looks consisting,essentially, of a plate, A, having corner-pieces a and a centfalstrengthening-ridge, c, and clampingscrews B B, O, and E, arrangedsubstantially as described.

2. As a new article of manufacture, the herein described lock attachmentconsisting, essentially, ofa-plate, A, formed with cornerpieces a a, aflange, b, ridge 0, bosses d d, and provided with screws B B. G, and E,the screw G being in turn provided with a buffer, D, connected theretoby a swiveljoint, 0, substantially as described.
